Eating, Laughing, Thinking, and Yawning
Twice the number of people eating equals half of the people who are laughing; if twenty people are thinking, and all of the people thinking are also all of the people laughing... and a quarter of the people laughing are also yawning, then how many people are yawning? How many people are eating?
